39 They answered and said to Him, “Abraham is our father.” Jesus said to them, “If you are Abraham’s children, do the deeds of Abraham. 40 But as it is, you are seeking to kill Me, a man who has told you the truth, which I heard from God; this Abraham did not do. 41 You are doing the deeds of your father.” They said to Him, “We were not born as a result of sexual immorality; we have one Father: God.” 42 Jesus said to them, “If God were your Father, you would love Me, for I came forth from God and am here; for I have not even come on My own, but He sent Me. 43 Why do you not understand what I am saying? It is because you cannot listen to My word. 44 You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he tells a lie, he speaks from his own nature, because he is a liar and the father of lies. 45 But because I say the truth, you do not believe Me. 46 Which one of you convicts Me of sin? If I speak truth, why do you not believe Me? 47 The one who is of God hears the words of God; for this reason you do not hear them, because you are not of God.”
48 The Jews answered and said to Him, “Do we not rightly say that You are a Samaritan, and You have a demon?” 49 Jesus answered, “I do not have a demon; on the contrary, I honor My Father, and you dishonor Me. 50 But I am not seeking My glory; there is One who seeks it, and judges. 51 Truly, truly I say to you, if anyone follows My word, he will never see death.” 52 The Jews said to Him, “Now we know that You have a demon. Abraham died, and the prophets as well; and yet You say, ‘If anyone follows My word, he will never taste of death.’ 53 You are not greater than our father Abraham, who died, are You? The prophets died too. Whom do You make Yourself out to be?” 54 Jesus answered, “If I glorify Myself, My glory is nothing; it is My Father who glorifies Me, of whom you say, ‘He is our God’; 55 and you have not come to know Him, but I know Him. And if I say that I do not know Him, I will be a liar like you; but I do know Him, and I follow His word. 56 Your father Abraham was overjoyed that he would see My day, and he saw it and rejoiced.” 57 So the Jews said to Him, “You are not yet fifty years old, and You have seen Abraham?” 58 Jesus said to them, “Truly, truly I say to you, before Abraham was born, I am.” 59 Therefore they picked up stones to throw at Him, but Jesus hid Himself and left the temple grounds.
I'm not entirely sure what to make of all of this.
What's clear is that this is saying that the devil is the father of the Jews. I'm not clear as to whether this is saying that Abraham is of the devil or not.
This looks almost like something that could come from a Marcionite, but not exactly. Marcion or Apelles would not refer to the devil I don't think.
Like Marcion, however, this associates judgment with evil, which is contrary to the orthodox position. The Jesus of John does not judge, he just provides forgiveness and eternal life. This has the devil as the judge. Marcion had the Jewish God as the judge. Many parts of John look like a Marcionite account in which "the devil" has taken the place of the Jewish Creator God. But in the Marcionite scheme, the Creator of the world was also the judge and was evil. In John Jesus is the Creator of the world, but he isn't a judge.
Most of the commentaries on this I don't find useful because they fail to address the Marcionite context in which John was likely produced and how it reflects the debates taking place in the middle of the second century, since even those who put a "late" date on John like to place it around 120 at the latest.
